TRANSFER ASSEMBLY Filed July 10, 1961 2 Sheets-Sheet 2 INVEINTOR James erdon; Kerr United States Patent 3,112,126 TRANSFER ASSEMBLY James Gordon Kerr, 9 Hardwell Road, Short Hilis, NJ. Filed July 10, 1961, Ser. No. 126,794 2 Claims. (Cl. 2S2-22) This invention relates to transfer assemblies, and more in particular to assemblies each comprising a sheet of one-time carbon paper and a sheet of copy paper. This invention is related to that disclosed in my Patent No. 2,557,875, issued June 19, 1951, and this application is a continuation-in-part of my pending application Serial No. 767,213, filed October 14, 1958, now abandoned.

An object of the present invention is to provide transfer assemblies of improved construction. A further object is to provide transfer assemblies which will be superior in withstanding the treatment and abuses which are encountered in storage, shipping, distribution and manual handling. A further object is to provide assemblies of the above character which overcome the difficulties which have been encountered with prior constructions. A further object is to provide such assemblies which are adaptable to various uses and which will not involve difiiculties which have developed in the use of some prior assemblies. These and other objects will be in part obvious and in part pointed out below.

FIGURE 10 is a front elevation with parts broken away and illustrating the production of transfer assemblies constituting one embodiment of the invention.

Referring to FIGURE 1 of the drawing, a transfer assembly 2 comprises a rectangular sheet 4 of one-time carbon paper and a sheet of copy paper 6 removably attached to each other by spot pasting by releasable paste spots 8 within the body of the copy paper. Sheet 6 is corner cut at the upper left-hand corner to form a vertical edge 12 which terminates in a short curve to the righthand edge of the sheet. The copy sheet 6 extends above and below the carbon sheet to provide exposed top and bottom margins or gripping areas 14 and 16, respectively. At the top and bottom of the carbon sheet 4, there are strips 18 and 21), respectively, which are free of carbon coating.

Assembly 2 is used in the manner illustrated in FIG- URE 2 by placing it beneath a sheet 22 of the same size which is a letterhead, but may be another original sheet. This complete assembly or duplicating set of FIGURE 2 is placed in the typewriter in the usual manner, and a letter is typed on sheet 22 with the carbon sheet 4 producing a copy on the copy sheet 6. Two or more assemblies 2 are used to make multiple carbon coplies. When assemblies 2 are being used with an orginal sheet, the top and bottom margins or strips 14 and 16 provide areas of selective grip for grasping the copy sheets without grasping the carbon sheets, while the cut-away portions at the corners of the copy sheets provide areas of selective grip for grasping the carbon sheets Without grasping the copy sheets.

3,112,126 Patented Nov. 26, 1963 If it is desirable to make an erasure during the typing operation, for example, to correct an error or change the text, the procedure is as illustrated in FIGURES 4 and 5. It is assumed that several assemblies 2 are being used to produce a corresponding number of carbon copies. To make an erasure, first the platen is advanced to move the area where the erasure is to be effected toward the top of the platen. The typist then grasps the group of sheets with the right-hand corner to the right of the vertical edges 12 of the copy sheets. In this way, all of the carbon sheets and the original sheet 22 are grasped, and the entire group is pulled forward as illustrated in FIGURE 4. However, the copy sheets are not grasped, but all except the bottom copy sheet are trapped between the carbon sheets. Thus, when the group is pulled forward, the bottom copy sheet 6 is not disturbed, and lies on the platen so that the erasure zone is exposed.

The erasure on this bottom copy sheet is then effected, and a shield or small strip of paper is placed over the erasure zone so as to protect the copy sheet during the efiecting of erasures on the sheets above it. The typist then uses the left-hand thumb and forefinger, as shown in FIGURE 5, to grasp the upper margins or strips 14 of the uncorrected copy sheets 6 and the original sheet 22, and moves this group of sheets back up over the platen. During this movement, the right-hand releases the righthand corners so that the bottom carbon sheet 4 is unsupported, and it drops onto the bottom copy sheet 6 which has been erased. While still holding the upper margins or strips 14, the typist then grasps the extreme upper righthand corner, as in FIGURE 4, with the right hand. However, the bottom carbon sheet 4 has now dropped down and only the remaining carbon sheets and the original sheet 22. are held with the right hand. The left hand is then released, and this permits the copy sheet 6 which is second from the bottom to fall. The group of sheets then grasped by the right hand is pulled again to the position of FIGURE 4, thus to expose the erasure area on the second to the bottom copy sheets; and, the erasure is effected. This procedure is repeated until all of the copy sheets have been erased. After each erasure is completed, the typist repeats the steps, first dropping off the next carbon sheet and then the next copy sheet, until the original is reached. It is thus seen that the erasing is applied progressively to all of the copies, starting with the bottom copy sheet, and no copy can be missed. During this procedure, the carbon-free upper edge 18 of the carbon sheet permits handling without dirtying the fingers. This process of automatic manipulation for the first time avoids the previous necessity of finger tip selection and separation of copies and carbons.

In the above reference to FIGURES 4 and 5, it will be noted that copies and carbons are shown being progressively manipulated and exposed from the last copy forward to the original. If it is desired to reverse this process, erasing the original first and then, progressively, each underlying copy, the alternating selective grip can be used quite as Well for this purpose.

In such case, following erasure of the original, it would be peeled or dropped forward and the balance of the record sheets gripped by two fingers of the left hand above the carbons. 'Ihen, with a forward flexing motion, the first carbon would be dropped forward against the original, using a soft pencil eraser (adequate for erasing the light deposit of one-time carbon) little pressure need be applied, and therefore no erasure shield .need be inserted behind the first record sheet as there is little or no smudging effect. Now, the extended corners of the carton are selectively grasped with the thumbs and prefinger of the right hand and flipped forward, thus automatically manipulating the first record sheet toward me previously deflected original and carbon sheet. The top 3 edges of the record sheets are now grasped with the left hand and the procedure repeated until all copies have been erased.

With the present invention the transfer assemblies are of the same size as an original, and super-imposed with areas of removable attachment and selective gripping within a sheet of the same size as an original, thereby avoiding projecting perforated stubs or carbon tissue with attendant difficulties of irregular detachment of the stub orcurling and folding of extended carbon tissue. The same over-all size for the transfer assembly and the original letterhead etc., makes it so that storage problems of different sized boxes will be avoided and supplies of both may be placed in desk trays or drawers built to accommodate the size of the original letterhead.

When the typing has been completed, the entire assembly is removed from the typewriter, and is held Bit the bot-tom as illustrated in FIGURE 3 by two fingers of the right hand. The original sheet 22 is readily peeled back,

as shown, and the carbon sheets 4 are grasped with the two fingers of the left hand at the upper left-hand corner to the left of the diagonal edge 10. In other versions of the assembly, the carbon 4 would be grasped by the fingers of the right hand at the upper right. A slight jerk or snap causes the carbon sheets 4 to pull away progressively at the pastedots 8 and to slide from the original and copy sheets.

It should be noted that the assembly 2 of the present invention is of the same size as the original or letterhead sheet, and may be stored and handled in the same mannor. During use, the original or letterhead sheet may be jogged with the assembly or assembly set so as to insure proper alignment. Each carbon sheet and its copy sheet is attached at the bottom but not at the top, and this gives advantages in handling and use. Furthermore, as explained above, erasures are made rapidly with selective grips which give progressive access to the sheets. The removal of the carbon sheets is rapid and is performed easily without danger and without chances of error. No perforated stubs are involved to project beyond the assembly, nor is there any risk of irregular detachment at such perforations with sections of the sheets torn off or pontions of the strip left attached and requiring subsequent removal. The paste spots are easily released, and the fingers are not soiled or smudged.

The absence of carbon coating on top and bottom margins of the carbon sheets does not interfere with the normal use because the typing is within the area of the carbon coating.

In the embodiment of FIGURE 6, the assembly 29 is identical with assembly 2 of FIGURE 1, except that the copy sheet 31 has a diagonal corner-edge 33 at the upper right-hand corner, and the smaller cut-away portion with the vertical edge 35 at the upper left-hand corner. The assembly 29 is used in the manner explained above, except that the user may separate the carbon sheets by grasping them at the upper right-h=and corner with the right hand, while holding the bottom edges of the original and copy sheets with the left hand.

In the embodiment of FIGURE 7, there is a single corner cut-out in the copy sheet 28 forming a somewhat angular line 30 which terminates in an arcuate curve. In the embodiment of FIGURE 8, the cut-out is provided at the center of the sheet, and is defined by an edge 50 having straight sides. In the embodiment of FIGURE 9, a semi-circular cut-out is provided in the righthand edge and is defined by an arcuate edge 52. It will be appreciated that the various embodiments of the invention here shown and modifications thereof may be useful to meet special conditions of actual use. With each of the illustrative embodiments of the invention, the copy sheet is of the exact size as the original sheet and the duplicating set comprising an original sheet and a plurality of assemblies may be jogged from any edge. The areas of selective grip are all within the borders of the original 4 sheet, and there are no protruding or extending tabs or stubs.

One mode of manufacturing the assembly of FIGURE 7 is represented in FIGURE 10. A web 32 of copy paper and a web 34 of carbon paper are represented as moving to the right, after having been assembled. During the assembly of the two webs, spot pasting is applied at the uncoated bottom edge of the carbon sheet to form the paste spots 36. Prior to (the assembly of the two webs, the web of copy paper is die-cut to produce spaced diecut lines 38 which are of the shape of the edge 30 in FIGURE 7. During the die-cutting operation, a hole 40 is also punched near the edge of the web immediately ahead of the die-cut line 38. As the two webs move to the right, the assemblies 42 of FIGURE 7 are formed by cutting at the lines 44. It should be noted that diecut 38 extends to the right beyond the cut-off line 44 at 46 for tolerance in the cut-off operation, so as to insure that the cut-out portion or tab 48 is always cnt free. As shown in FIGURE 7, the extension 46 of the die-cut line 38 occurs at the left-hand margin of the copy sheet.

The invention contemplates that the cut-01f be by a rotary knife which is located by relay circuitry with respect to the die-cuts 38 of the web. The punched-out holes 49 may be used to control and synchronize the cutoff operations by providing an electric eye which operates the knife when one of the holes 40 is sensed. A picker projects through each of the holes 40 to remove the cutoff portion or tab 48. A large number of the copy paper webs 32 and the carbon paper webs 34 are assembled together and cut simultaneously.

As many possible embodiments may be made of the mechanical features of the above invention and as the art herein described might be varied in various parts, all without departing from the scope of the invention, it is to 'be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
